strip of carpet, narrower than the width of the stairsjand applied over the treads and risers, being held by tacks at the bottoms of the risers or by rods through which are ssednaili Q1 like securing; means of a [i -ted, durin nature, making the removal or; the carpet ditlicult and mutilating the stair way in either case.

It is therefore one of the objects this invention to provide a stair rod that is fully capable of securing carpet in place on a 'stair-way, without driving nails or the like, no toolsbeing reguired, and which can be as realily removed to release the carpet, either operation taking the briei'est possible time.

A further feature is in the provision of a stair rod capable of being a ppiied or removed without mutilation or disfigurement oi the carpet or stair-way, the operation being so simple that .it can be accomplished by a novice without diiiiculty.

Another purpose is to produce a stair rod composed oi? essentially simple and inexpensive parts, light in weight having abundant strength and possessing neat and attractive appearance.

These several advantageous objects are obtained by the novel construction and combi' nation of parts hereinafter described and shown in the annexed drawing forming a material part of this disclosure, and in which Figure 1 iso front elevational view of a portion of a conventional stair-way illustrating the application of t 1e invention.

Figure 2 is a side elevational view of the same.

Figure 3 is a. partial side view of an embodinient of the stair rod, shown in a raised position prior to attachment, parts being in section.

Figure 4%: is a similar view of the rod a ord'ended straight.

inv Figures 1 and 2 a pair of inclined sides, ordinarily made of wood, are designated by the numeral 5 between which are a flight of stairs composed of horizontal treads and U risers 7, shown as covered by a carpet 8, of lesser width than the distance between the stair side, all being of the usual and. well known construction.

Staircoverings usually consist of a single 30., rear. Serigd 235, 66.

The invention consists of a stair rod, generally designated by the numeral 9 i and shown in uetarl in Figures 3 and 4.

Each stair rod unit consists of two tubular sections it), each section having rigidly secured. in one end a plug 11 which is entered within the tube to leave a short space at the end, and fixed in the plugs are eyes 12 intercngzagred in the manner of a hinge, permitting the tubes to be disposed at an angle, as shown in the broken lines on thetop step in Figure 1, and better in the detail View in Figure 3. i

j I A plurality of spaced transverse perforat onslii are made in the opposite outer portions of the tubes. in which are slidably throi 1 which is passed a headed pin 15 to adjustably retain the element 14: within the tube.

Set in the outer ends of the adjustable eleare the shanks oi. convex cushion 16, preferably made of rubber, and n1: axially outward from these memsharply pointed fixed spurs 17, adapted to f. rce the stair sides 5 to the limit of the cushions 16.

in order to hold the tubular members 10 in alinenieru: when fixed in position, a telescopic tube or elongated sleeve 18 is arranged slidably thereon, the same extending over the hinged central joint, acting to maintain the same rigid when extended straight out and also to completely obscure the joint.

In operation the elements 141- are adjusted by the pins 15 so that the distance between the cushions 1-5, when the device is extended straight, will closely approximate the distance between the sides oi the stair-way.

'lhereupon, the carpet having been adto one side or the other, the joint formed by the eyes 12 turned upward and the spurs 17 set in the wood work in such manner as to press the carpet into the angle between the tread and riser of the stair.

Obviously by exerting moderate pressure upon the raised joint, the rod will become straight, permitting the sleeve to be moved over the joint and retain the carpet in its proper adjustment.

It will be equally apparent that the carpet can be removed by reversing; the foregoing operations and that no possible damage is done the carpet or the wood work, other than the mere'perforations of the spurs 17, as the cushions 16 provide against abrasion.

ters Patent, is: r

1. i A stair rod coi'nposed of two tubular sections jointed atone end to permit relative angular motion, rods telescopically engaged in the opposite ends of said tubular sections,

means to retain said rods in adjustment therein, cushion elements at the outer endsot' said rods, spurs protruding from said cushions, and a sleeve slidable over the oint between i said sections.

2. stair rod composed of a pair of tubes having plugs fixed in their ad acent ends, eyes set in said plugs, said eyes being interengaged to permit relative angular movement of the tubes, a sleeve slidable over the adjacent ends of said tubes, rods adjustably secured in the opposite ends of the tubesyand sharply pointed spurs'at the outer ends of said rods.

3. A stair rod composed of two equal members having a universal joint connecting t-herebetwecn, a slide on said members to retain the joint rigid when moved thereover, adjustable element slidable in said members, cushions at the outer ends of said members, and prong-s extending axially through the cushions.

4:. A stair rod comprising a pair of tubes having a universal joint therebetwccn, means for maintaining said joint rigid when the tubes are in register, telescopic rods movable in said tubes, means for fixing said rods in adjustment, cushions on the ends of said rods, and sharply pointed prongs extending from said cushions.

5. A. stair rod composed of two universally jointed members, rods adjustably secured therein, said rods being adapted to extend longitudinally the full width of a. stairway, cushions at the ends of said rods to engage he sides of the stair way, and means in said cushions to enter the stair \vay sides to retain the rod fixedly therebetvvcen.

In testimony whereof I afiix my signature.
